[英]JSON Schema oneOf properies filled
How to set JSON Schema rule to say that exactly one of the properties have to be set and is required? 如何设置JSON Schema规则以确定必须设置其中一个属性并且是必需的?
I tried various ways to solve it like: 我尝试了各种方法来解决它:
{
"id":"#",
"required":true,
"additionalProperties":true,
"type":"object",
"properties":{
"surname":{
"id":"surname",
"required":true,
"type":"string"
},
"oneOf":[
{
"$ref":"#/definitions/station_id"
},
{
"$ref":"#/definitions/station"
}
]
},
"definitions":{
"station_id":{
"type":"integer"
},
"station":{
"type":"string"
}
}
}
But it never worked. 但它从来没有奏效。 What I need to do is to accept either station_id what is an integer or station what is a string name.
我需要做的是接受station_id什么是整数或者什么是字符串名称。
Is there a way to do that, please? 请问有办法吗?
oneOf
is only special when used directly inside a schema. oneOf
仅在模式中直接使用时才是特殊的。 When you use oneOf
inside properties
, then it has no special meaning, so you actually end up defining a property called "oneOf"
instead. 当你在内部
properties
使用oneOf
,它没有特殊含义,所以你实际上最终定义了一个名为"oneOf"
的属性。
Also - it's not the property definitions that make something required, it's the required
keyword. 此外 - 不是必需的属性定义,它是
required
关键字。 This keyword is an array of required properties (not a boolean, that's old syntax). 此关键字是必需属性的数组(不是布尔值,即旧语法)。
To do what you want, you make a oneOf
clause where one option has "station_id"
required, and the other has "station"
required: 要做你想做的事,你做一个
oneOf
子句,其中一个选项需要"station_id"
oneOf
,另一个选项需要"station"
:
{
"oneOf": [
{"required": ["station"]},
{"required": ["station_id"]}
]
}
If both are present, then the data will be invalid (because only one oneOf
entry is allowed to pass). 如果两者都存在,则该数据将被无效(因为只有一个
oneOf
条目被允许通过)。
